Description:

[0001] Pursuant to 35 U.S.C. §119(a), this application claims the
benefit of earlier filing date and right of priority to Korean
Application 10-2011-0019311 filed on Mar. 4, 2011, the content of which
is incorporated by reference herein in its entirety.

BACKGROUND

[0002] 1. Field of the Invention

[0003] The present disclosure relates to a display device and a portable
information apparatus including the same, and more particularly, to a
display device and a portable information apparatus including the same,
which do not use a front set cover necessary for producing the display
device and thus can minimize a thickness and enhance a sense of beauty
with an innovative design.

[0006] In terms of technology and design interesting to consumers,
recently, research and development of flat panel display devices are
increasingly required. Therefore, efforts are being continuously made for
minimizing (slimming) the thicknesses of display devices, and research is
increasingly conducted on a design with enhanced sense of beauty that can
induce consumers to buy by appealing to the consumers' sense of beauty.

[0007] However, in design development for enhancing a scene of beauty or
slimming of display devices that have been made to date, elements
configuring a related art display device have been applied as is, and the
structures of the elements have been changed. Due to these reasons, there
are limitations in slimming display devices and developing the new
designs of the display devices.

[0008] For example, in LCD devices of the related art, a lower case and a
front case are necessarily used for receiving a liquid crystal display
panel and a backlight unit, and moreover, a separate front set cover and
rear set cover are additionally used for applying the LCD devices to
notebook computers, monitors, mobile devices, televisions, etc. As
described above, display devices of the related art necessarily use the
front set cover and rear set cover as well as the lower case and front
case, and consequently, there are limitations in reducing the thicknesses
of LCD devices or changing the designs thereof. Particularly, the front
set cover and rear set cover necessarily cover a top edge of a liquid
crystal display panel. Due to this reason, the thicknesses of display
devices inevitably become thicker, and moreover, the border widths of the
display devices enlarge. In addition, it is difficult to realize various
innovative designs due to a step height in a border portion.

which is prepared by a set plate and a set side wall; a guide frame
coupled to the set cover, and placed in the receiving space; a display
unit including a display panel which is adhered to the guide frame; a
circuit disposing part prepared between one side of the guide frame and
one side wall of the set side wall; a plurality of circuit films
connected to the display panel; a Printed Circuit Board (PCB) connected
to the circuit films, and disposed at the circuit disposing part; and a
deco cover covering the circuit disposing part.

[0010] In another aspect of the present invention, there is provided a
portable information apparatus including: a system body; and a display
device rotatably coupled to the system body by a hinge part, wherein the
display device includes: a set cover including a receiving space which is
prepared by a set plate and a set side wall; a guide frame coupled to the

EMBODIMENTS

[0021] Reference will now be made in detail to the exemplary embodiments
of the present invention, examples of which are illustrated in the
accompanying drawings. Wherever possible, the same reference numbers will
be used throughout the drawings to refer to the same or like parts.

[0022] Hereinafter, a display device and a portable information apparatus
including the same will be described with reference to the accompanying
drawings.

[0023] FIG. 1 is a view for describing a display device according to an
embodiment of the present invention, which is used in monitors,
televisions, and portable information apparatuses. FIG. 2 is an exploded
perspective view schematically illustrating a display device according to
a first embodiment of the present invention. FIG. 3 is a sectional view
illustrating a sectional surface taken along line A-A' of FIG. 1, and
illustrates the display device according to the first embodiment of the
present invention.

[0024] Referring to FIGS. 1 to 3, the display device according to the
first embodiment of the present invention includes a set cover 100 having
a receiving space that is prepared by a set plate 110 and a set side wall
120, a guide frame 200 that is disposed at the set cover 100 and placed
in the receiving space, a display unit 300 including a display panel 310
that is disposed at the guide frame 200, a circuit disposing part 330
that is prepared between one side of the guide frame 200 and one side
wall of the set side wall 120 parallel to the one side of the guide frame
200, a plurality of circuit films 340 that are disposed at the circuit
disposing part 330 to contact the display panel 310, a Printed Circuit
Board (PCB) 350 that is disposed at the circuit disposing part 330 to
contact the circuit films 340, and a deco cover 400 that covers the
circuit disposing part 330.

[0025] The set cover 100 is formed in a tetragonal frame shape to support
the guide frame 200 and surround a side of the guide frame 200, and thus
acts as a product cover of a produced display device. Herein, the set
cover 100 may be formed of a plastic material or a metal material, for
example, formed of a metal material for enhancing a sense of beauty of
the produced display device.

[0026] The set plate 110 has a flat shape, and acts as a rear cover of a
produced display device

[0027] The set side wall 120 is bent vertically from the set plate 110 to
form the receiving space. The set side wall 120 is formed to surround the
side of the guide frame 200, and acts as a side cover of the produced
display device.

[0028] The guide frame 200 is placed in the receiving space that has been
prepared at the set cover 100, and supports the display unit 300. For
this end, the guide frame 200 includes a guide side wall 210, a
supporting part 220, and a plurality of frame coupling members 230.

[0029] The guide side wall 210 is vertically formed in parallel to the set
side wall 120, and surrounds a side of the display unit 300. Herein, an
upper surface of the guide side wall 210 surrounds the side of the
display unit 300, in which case the upper surface of the guide side wall
210 is exposed to the outside so as not to overlap with an upper edge
portion of the display unit 300 and thus forms a border of the display
unit 300.

[0030] On the one hand, a short side of the guide frame 200 is formed
shorter than the length of a short side of the set cover 100, and thus,
one side of the guide side wall 210 is separated from the set side wall
120 by a certain distance. Therefore, the circuit disposing part 330 is
prepared between one side of the guide frame 200 and one side wall of the
set side wall 120 parallel to the one side of the guide frame 200.

[0031] On the other hand, a plurality of concave portions 212 with the
circuit films 340 disposed therein are formed at a top of one side of the
guide side wall 210 adjacent to the circuit disposing part 330.

[0032] The supporting part 220 protrudes from the guide side wall 210 in
the opposite direction of the set side wall 120 to have a stepped shape,
and supports the display unit 300.

[0033] The frame coupling members 230 are formed at certain intervals to
have a hook or protrusion shape, at sides other than one side of the
guide frame 200. The frame coupling members 230 are coupled to the set
side wall 120 and thus allow the guide frame 200 to be coupled to the set
cover 100. In this case, a plurality of coupling grooves 122 respectively
coupled to the frame coupling members 230 are formed at an inner surface
of the set side wall 120.

[0034] The above-described guide frame 200 is formed to have the same
color as color that is displayed when the display unit 300 is not driven.
For example, the guide frame 200 may be formed in black.

[0035] The display unit 300 is placed in the supporting part 210 that is
formed in a stepped shape at the guide frame 200, and surrounded by a top
of the guide side wall 210. The display unit 300 includes a display panel
310.

[0036] The display panel 310 may be a liquid crystal display panel or an
organic light emitting display panel that includes a facing-coupled lower
substrate 312 and upper substrate 314.

[0037] In an embodiment, when the display panel 310 is the liquid crystal
display panel, the display unit 300 may further include a backlight unit
320 for irradiating light on the liquid crystal display panel 310, a
lower polarizer 316 adhered to the lower substrate 312, and an upper
polarizer 318 adhered to entire one surface of the upper substrate 314.

[0038] Moreover, when the display panel 310 is the liquid crystal display
panel, the supporting part 220 of the guide frame 200 is formed in a
stepped shape, and includes a backlight disposing part 222 for supporting
the backlight unit 320, and a panel disposing part 224 for supporting the
liquid crystal display panel 310. In this case, the liquid crystal
display panel 310 is adhered to the panel disposing part 224 by the
adhesive member 250. Herein, the adhesive member 250 may be a
double-sided tape or an adhesive (for example, a glue, an instant
adhesive, a thermosetting adhesive, or a photocurable adhesive).

[0039] The backlight unit 320 is placed in the backlight disposing part
222 of the guide frame 200, and includes a reflective sheet 322, a light
guide panel 324, and an optical member 326.

[0040] The reflective sheet 322 is disposed at a bottom of the backlight
disposing part 222, and reflects light, incident from the light guide
panel 324, to the liquid crystal display panel 310.

[0041] The light guide panel 324 is formed in a flat shape and guides
light, incident from a light source (not shown) to a light incident
surface, to the liquid crystal display panel 310. Herein, the light
source may include at least one fluorescent lamp or a Light Emitting
Diode (LED).

[0042] The optical member 326 is disposed on the light guide panel 324 and
enhances the luminance characteristic of light traveling from the light
guide panel 324 to the display panel 310. For this end, the optical
member 326 may include at least two of a lower diffusive sheet, a lower
prism sheet, an upper prism sheet, and an upper diffusive sheet.

[0043] In another embodiment, when the display panel 310 is the organic
light emitting display panel, the display unit 300 may further include
the upper polarizer 318 adhered to entire one surface of the upper
substrate 314.

[0044] The circuit films 340 contacts the display panel 310 and is
disposed at the concave portions 212 and the circuit disposing part 330.
Herein, the circuit films 340 may be adhered to the lower substrate 110
and PCB 350 of the display panel 310 by a Tape Automated Bonding (TAB)
process, and may be a Tape Carrier Package (TCP) or Chip On Flexible
Board/Chip On Film (COF). Therefore, the display panel 310 is
electrically connected to the PCB 350 through the circuit films 340.

[0045] A data driving Integrated Circuit (IC) 345 for supplying data
signals to the display panel 310 are mounted on each of the circuit films
340. Furthermore, a gate driving circuit (not shown) for supplying a gate
(scan) signal to the display panel 310 is built in the lower substrate
312 of the display panel 310.

[0046] The PCB 350 is electrically connected to the circuit films 340 and
disposed at the set plate 110 corresponding to the circuit disposing part
330. A timing controller (not shown) for controlling driving of the
display panel 310, various power source circuits (not shown), a memory
element (not shown), etc. are mounted on the PCB 350.

[0047] The deco cover 400 is coupled to one side wall of the set side wall
120 and one side of the guide frame 200 to cover a space (namely, the
circuit disposing part 330) between the one side of the guide frame 200
and the one side wall of the set side wall 120 parallel to the one side
of the guide frame 200, thereby protecting the PCB 350 and the circuit
films 340. For this end, the deco cover 400 includes a cover plate 410,
and a plurality of first and second coupling members 420 and 430.

[0048] The cover plate 410 covers the circuit disposing part 330 so as not
to expose the circuit films 340 and PCB 350, disposed at the circuit
disposing part 330, to the outside.

[0049] The first coupling members 420 are formed at certain intervals, at
one side of the cover plate 410 and coupled to one side wall of the set
side wall 120. Herein, each of the first coupling members 420 is formed
vertically from one side rear surface of the cover plate 410 to have a
protrusion or hook shape. Furthermore, the set cover 100 includes a
plurality of hook coupling grooves 130 that are formed at one side wall
of the set side wall 120 to be coupled to the first coupling members 420.

[0050] The second coupling members 430 are form at the other side of the
cover plate 410 to correspond to respective gaps between the circuit
films 340, and coupled to the guide side wall 210 of one side of the
guide frame 200. Herein, each of the second coupling members 430 is
formed vertically from the other side rear surface of the cover plate 410
to have a protrusion or hook shape. Furthermore, the guide frame 200
includes a plurality of third coupling members 240 that are formed at one
side of the guide side wall 210 to be coupled to the second coupling
members 430.

[0051] The PCB 350 further includes a plurality of through holes 352 which
are formed in correspondence with the second coupling members 430 and
through which the second coupling members 430 respectively pass in
assembling the deco cover 400.

[0052] In the first embodiment of the present invention, the display unit
300 is adhered to the guide frame 200 by the adhesive member 250, the
guide frame 200 is coupled to the set cover 100, and thus, a lower case
and upper case of the related art and a front cover of each product are
not applied to the first embodiment. Accordingly, an entire thickness T
of the display device can be reduced, a width W of a front frame portion
can be minimized, and thus, provided can be the display device having an
innovative design with enhanced sense of beauty.

[0053] Moreover, in the first embodiment of the present invention, the
circuit disposing part 330 is prepared at one side of the set cover 100,
and the deco cover 400 covers the circuit film 340 and PCB 350 that are
disposed at the circuit disposing part 330. Accordingly, the circuit film
340 and PCB 350 are prevented from being exposed to the outside, and
thus, design limitations that are caused by not using an upper case of
the related art and a front cover of each product can be solved.

[0054]FIG. 4 is a sectional view illustrating a sectional surface taken
along line A-A' of FIG. 1, and illustrates a display device according to
a second embodiment of the present invention.

[0055] Referring to FIGS. 1, 2 and 4, the display device according to the
second embodiment of the present invention includes the set cover 100,
the guide frame 200, the display unit 300, the circuit disposing part
330, the plurality of circuit films 340, the PCB 350, the deco cover 400,
and a sealing member 450. Except that the display device of the second
embodiment further includes the sealing member 450 compared to the first
embodiment, the second embodiment having such a configuration has the
same configuration as that of the first embodiment of FIGS. 1 to 3, and
thus, the above description of the first embodiment is applied to the
same elements. Like reference numerals refer to like elements throughout.

[0056] First, in manufacturing the display unit, namely, the display panel
310 and the guide frame 200, since a process error occurs in
manufacturing, a gap due to the process error is formed between a side of
the display panel 310 and the guide side wall 210 of the guide frame 200.

[0057] The sealing member 450 seals the gap between the side of the
display panel 310 and the guide side wall 210, and thus prevents foreign
substances such as dust from being penetrated into the inside through the
gap and prevents a sense of beauty from being degraded by the gap.
Herein, the sealing member 450 is formed in the same color as that of the
guide frame 200 such that an aesthetic effect is not degraded by a color
difference between the sealing member 450 and the guide frame 200.

[0058] A sealing member 450 according to an embodiment may be formed in a
ring or flat shape. The sealing member 450 is inserted into the gap
between the side of the display panel 310 and the guide side wall 210,
and thus seals the gap.

[0059] A sealing member 450 according to another embodiment may be a
silicon resin or an ultraviolet (UV)-setting resin. The sealing member
450 is charged into the gap between the side of the display panel 310 and
the guide side wall 210 by a dispenser (not shown), and seals the gap by
being hardened.

[0060] The display device of the second embodiment can provide the same
effect as that of the display device of the first embodiment. Also, in
the second embodiment, the sealing member 450 seals the gap between the
side of the display panel 310 and the guide side wall 210, and thus
prevents foreign substances such as dust from being penetrated into the
inside through the gap and prevents a sense of beauty from being degraded
by the gap.

[0061] FIG. 5 is an exploded perspective view schematically illustrating a
display device according to a third embodiment of the present invention.
FIG. 6 is a sectional view illustrating a sectional surface taken along
line A-A' of FIG. 1, and illustrates the display device according to the
third embodiment of the present invention.

[0062] Referring to FIGS. 1, 5 and 6, the display device according to the
third embodiment of the present invention includes the set cover 100, the
guide frame 200, the display unit 300, the circuit disposing part 330,
the plurality of circuit films 340, the PCB 350, a deco cover 1400, and a
supporting frame 1500. Except that one side of the guide frame 200 is
fixed by the supporting frame 1500 and the deco cover 1400 is coupled to
the supporting frame 1500 and the guide frame 200, the third embodiment
having such a configuration has the same configuration as that of the
first embodiment of FIGS. 1 to 3, and thus, the above description of the
first embodiment is applied to the same elements. Like reference numerals
refer to like elements throughout.

[0063] First, the supporting frame 1500 is disposed at the set plate 110
and set side wall 120 corresponding to the circuit disposing part 330 so
as to be coupled to the deco cover 1400. In this case, the supporting
frame 1500 is adhered to the set plate 110 and set side wall 120
corresponding to the circuit disposing part 330 by an adhesive member
such as a double-sided tape or an adhesive. The supporting frame 1500
supports the PCB 350 that is disposed at the circuit disposing part 330.
For this end, the supporting frame 1500 includes a front plate 1510, a
supporting side wall 1520, a supporting plate 1530, and a plurality of
first coupling protrusions 1540.

[0064] The front plate 1510 is disposed at a top of the set side wall 120
adjacent to the circuit disposing part 330.

[0065] The supporting side wall 1520 is bent from the front plate 1510 to
contact an inner wall of the set side wall 120 adjacent to the circuit
disposing part 330. The supporting side wall 1520 may be adhered to the
inner wall of the set side wall 120 by the adhesive member.

[0066] The supporting plate 1530 is bent from the supporting side wall
1520 to be disposed at the set plate 110 corresponding to the circuit
disposing part 330. The supporting plate 1530 is adhered to the set plate
110 corresponding to the circuit disposing part 330 by the adhesive
member. Herein, a certain shape of blank may be formed at the supporting
plate 1530, for reducing a weight.

[0067] The first coupling protrusions 1540 protrude vertically from the
supporting plate 1530 adjacent to one side of the guide frame 200 to have
a hook shape. The first coupling protrusions 1540 are coupled to one side
of the guide frame 200 disposed at the set plate 110, and thus fix the
guide frame 200.

[0068] The guide frame 200 further includes a plurality of second coupling
protrusions 242 that are formed at one side of the guide side wall 210 to
be coupled to the first coupling protrusions 1540. Therefore, the guide
frame 200 is coupled to the set cover 100 by coupling of the frame
coupling members 230 (which are formed at an outer side of the guide side
wall 210 other than the guide side wall 210 adjacent to the circuit
disposing part 330) and the coupling grooves 122 formed at an inner
surface of the set side wall 120, and coupled to the supporting frame
1500 by coupling of the first coupling protrusions 1540 and the second
coupling protrusions 242.

[0069] The deco cover 1400 is coupled to the supporting side wall 1520 of
the supporting frame 1500 and one side of the guide frame 200 to cover
the circuit disposing part 330, and thus protects the PCB 350 and circuit
films 340 disposed at the circuit disposing part 330. For this end, the
deco cover 1400 includes a cover plate 1410, a plurality of first
coupling members 1420, and a plurality of second coupling members 1430.

[0070] The cover plate 1410 covers the circuit disposing part 330 so as
not to expose the PCB 350 and circuit films 340 disposed at the circuit
disposing part 330 to the outside.

[0071] The first coupling members 1420 are formed at certain intervals, at
one side of the cover plate 1410 and coupled to the supporting side wall
of the supporting frame 1500. Herein, each of the first coupling members
1420 is formed vertically from one side rear surface of the cover plate
1410 to have a protrusion or hook shape. Furthermore, the supporting
frame 1500 includes a plurality of hook coupling grooves 1522 that are
formed at an inner side wall of the supporting side wall 1520 to be
coupled to the first coupling members 1420.

[0072] The second coupling members 1430 are form at the other side of the
cover plate 1410 to correspond to respective gaps between the circuit
films 340, and coupled to the guide side wall 210 of one side of the
guide frame 200. Herein, each of the second coupling members 1430 is
formed vertically from the other side rear surface of the cover plate
1410 to have a protrusion or hook shape. Furthermore, the guide frame 200
includes a plurality of third coupling members 240 that are formed at one
side of the guide side wall 210 to be coupled to the second coupling
members 1430.

[0073] On the one hand, the second coupling members 1430 may be coupled to
the coupling protrusions 1540 that are formed at the supporting frame
1500, instead of the third coupling member 240 of the guide frame 200. In
this case, the deco cover 1400 is coupled only to the supporting frame
1500, and thus, the second coupling protrusions 242 formed at the guide
frame 200 are not provided.

[0074] On the other hand, the display device of the third embodiment may
further include a sealing member 450 that seals the gap between the side
of the display panel 310 and the guide side wall 210.

[0075] The sealing member 450 seals the gap between the side of the
display panel 310 and the guide side wall 210, and thus prevents foreign
substances such as dust from being penetrated into the inside through the
gap and prevents a sense of beauty from being degraded by the gap.
Herein, the sealing member 450 is formed in the same color as that of the
guide frame 200 such that an aesthetic effect is not degraded by a color
difference between the sealing member 450 and the guide frame 200.

[0076] The display device of the third embodiment can provide the same
effect as that of the display device of the first embodiment. Also, in
the third embodiment, by coupling the guide frame 200 to the set cover
100 and the supporting frame 1500, a coupling strength of the guide frame
200 can increase.

[0077]FIG. 7 is a view schematically illustrating a portable information
apparatus according to an embodiment of the present invention. FIG. 8 is
an exploded perspective view schematically illustrating the display
device of FIG. 7.

[0078] Referring to FIGS. 7 and 8, the portable information apparatus
according to an embodiment of the present invention includes a system
body 500, and a display device 700 that is rotatably coupled to the
system body 500 by a hinge part 600.

[0079] The system body 500 includes a control circuit for processing

[0080] The hinge part 600 is disposed between one side of the system body
500 and a lower portion of the display device 700 such that display
device 700 is rotatably coupled to the system body 500. For this end, the
hinge part 600 includes a hinge axis 610, and first and second brackets
620 and 630 that are rotatably disposed at one side of the hinge axis
610.

[0081] The hinge axis 610 and the first bracket 620 are coupled to the
display device 700, and the second bracket 630 is coupled to the system
body 500.

[0082] The display device 700 includes; the set cover 100 having a
receiving space that is prepared by the set plate 110 and the set side
wall 120; the guide frame 200 that is disposed at the set cover 100 and
placed in the receiving space; the display unit 300 including the display
panel 310 that is disposed at the guide frame 200; the circuit disposing
part 300 that is prepared between one side of the guide frame 200 and the
one side wall of the set side wall 120 parallel to the one side of the
guide frame 200; the PCB 350 that is disposed at the circuit disposing
part 330 to be connected to the circuit films 340 and the system body
500; the supporting frame 1500 that is disposed at the circuit disposing
part 330 and one side wall of the set side wall 120 and supports the
hinge part 600 and the PCB 350; and the deco cover 1400 that covers the
circuit disposing part 330. Except for the supporting frame 1500 and the
deco cover 1400, the display device 700 having such a configuration has
the same configuration as that of the third embodiment of FIGS. 5 and 6,
and thus, the above description of the third embodiment is applied to the
display device 700. Like reference numerals refer to like elements
throughout.

[0083] First, the supporting frame 1500 is disposed at the set plate 110
and set side wall 120 corresponding to the circuit disposing part 330 so
as to be coupled to the deco cover 1400. In this case, the supporting
frame 1500 is adhered to the set plate 110 and set side wall 120
corresponding to the circuit disposing part 330 by an adhesive member
such as a double-sided tape or an adhesive. The supporting frame 1500
supports the PCB 350 that is disposed at the circuit disposing part 330.
For this end, the supporting frame 1500 includes the front plate 1510,
the supporting side wall 1520, the supporting plate 1530, the plurality
of first coupling protrusions 1540, and a hinge supporting part 1550.
Except for the hinge supporting part 1550, the supporting frame 1500
having such a configuration has the same configuration as that of the
third embodiment, and thus, the above description of the third embodiment
is applied to the supporting frame 1500. Like reference numerals refer to
like elements throughout.

[0084] The hinge supporting part 1550 is provided at both edge portions of
the supporting plate 1530 to have a certain height in correspondence with
the hinge part 600 and supports the hinge part 600. In this case, the
hinge axis 610 of the hinge part 600 is rotatably disposed at the hinge
supporting part 1550, and the first bracket 620 of the hinge part 600 is
coupled to the set plate 110. The second bracket 630 of the hinge part
600 is coupled to the system body 500.

[0085] The deco cover 1400 is coupled to the supporting side wall 1520 of
the supporting frame 1500 and one side of the guide frame 200 to cover
the circuit disposing part 330, and thus protects the PCB 350 and circuit
films 340 disposed at the circuit disposing part 330. For this end, the
deco cover 1400 includes a cover plate 1410, a plurality of first
coupling members 1420, a plurality of second coupling members 1430, and a
hinge cover 1440.

[0086] The cover plate 1410 covers the circuit disposing part 330 so as
not to expose the PCB 350 and circuit films 340 disposed at the circuit
disposing part 330 to the outside. In this case, a through portion 1412
through which the hinge supporting part 1550 passes is formed at the
cover plate 1410 corresponding to the hinge supporting part 1550 of the
supporting frame 1500.

[0087] The first coupling members 1420 are formed at certain intervals, at
one side of the cover plate 1410 and coupled to the supporting side wall
of the supporting frame 1500. Herein, each of the first coupling members
1420 is formed vertically from one side rear surface of the cover plate
1410 to have a protrusion or hook shape. Furthermore, the supporting
frame 1500 includes a plurality of hook coupling grooves 1522 that are
formed at an inner side wall of the supporting side wall 1520 to be
coupled to the first coupling members 1420.

[0088] The second coupling members 1430 are form at the other side of the
cover plate 1410 to correspond to respective gaps between the circuit
films 340, and coupled to the guide side wall 210 of one side of the
guide frame 200. Herein, each of the second coupling members 1430 is
formed vertically from the other side rear surface of the cover plate
1410 to have a protrusion or hook shape. Furthermore, the guide frame 200
includes a plurality of third coupling members 240 that are formed at one
side of the guide side wall 210 to be coupled to the second coupling
members 1430.

[0089] On the one hand, the second coupling members 1430 may be coupled to
the coupling protrusions 1540 that are formed at the supporting frame
1500, instead of the third coupling member 240 of the guide frame 200. In
this case, the deco cover 1400 is coupled only to the supporting frame
1500, and thus, the second coupling protrusions 242 formed at the guide
frame 200 are not provided.

[0090] The hinge cover 1440 is provided at the cover plate 1410 in
correspondence with the hinge supporting part 1550 that is provided at
the supporting frame 1500, and coupled to the hinge supporting part 1550.
Herein, the hinge supporting part 1550 and the hinge cover 1440 are
coupled with each other by a hook. Therefore, the hinge axis 610 of the
hinge part 600 and the first bracket 620 are covered by the hinge cover
1440, and the second bracket 630 of the hinge part 600 is exposed to the
outside to be coupled to the system body 500.

[0091] Furthermore, the display device 700 may further include a sealing
member 450 that seals the gap between the side of the display panel 310
and the guide side wall 210.

[0092] The sealing member 450 seals the gap between the side of the
display panel 310 and the guide side wall 210, and thus prevents foreign
substances such as dust from being penetrated into the inside through the
gap and prevents a sense of beauty from being degraded by the gap.
Herein, the sealing member 450 is formed in the same color as that of the
guide frame 200 such that an aesthetic effect is not degraded by a color
difference between the sealing member 450 and the guide frame 200.

[0093] The portable information apparatus according to an embodiment of
the present invention may be a notebook computer. In this case, a
thickness of the display device of the notebook computer and a width W of
a front frame portion can be minimized, and thus, provided can be the
notebook computer having an innovative design with enhanced sense of
beauty.

[0094] According to the embodiments of the present invention, the display
unit is adhered to the guide frame by the adhesive member, the guide
frame is coupled to the set cover, and thus, the lower case and upper
case of the related art and the front cover of each product are not
applied to the embodiments. Accordingly, the entire thickness of the
display device can be reduced, the width of the front frame portion can
be minimized, and thus, provided can be the display device having an
innovative design with enhanced sense of beauty.

[0095] Moreover, by covering the circuit film and PCB with the deco cover,
the circuit film and PCB are prevented from being exposed to the outside,
and thus, design limitations that are caused by not using the upper case
of the related art and the front cover of each product can be solved.

[0096] Moreover, by sealing the gap between the guide side wall and the
side of the display panel with the sealing member, foreign substances
such as dust can be prevented from being penetrated into the inside
through the gap, and a sense of beauty can be prevented from being
degraded due to the gap.

[0097] It will be apparent to those skilled in the art that various
modifications and variations can be made in the present invention without
departing from the spirit or scope of the inventions. Thus, it is
intended that the present invention covers the modifications and
variations of this invention provided they come within the scope of the
appended claims and their equivalents.
